9 Claims.

This invention relates to the splicing of a running web to a rotatingfresh web roll chiefly for printing presses.

The principal objects of the invention are to provide for the keeping ofthe fresh web roll free from adhesive on its outer surface while it lsbeing speeded up so that it can be rotated by moving means in contactwith its surface Without danger of getting the adhesive on the saidmoving means and to permit the use for rotating this roll of theordinary running belts which are normally used for tension, and toprovide mechanism for supplying the adhesive to the running web orrunning roll or both at the proper moment.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which- 90 Fig. 1is an end View of a well known type of magazine reel used for splicingwith a preferred embodiment of this invention applied thereto;

Fig. 2 is an elevation thereof, and

Fig. 3 is an end view showing a modification of the method of applyingthe adhesive.

In the forms shown in Figs. 1 and 2 is illustrated, as stated, anordinary three-armed spider constituting part of a rotary reel forsupporting the fresh web roll S and the running roll n0 R. Tension beltsI are employed passing over a series of idlers. These belts are operatedby a series of pulleys using power from the press to drive the belts inthe proper proportion to the speed of the web. Weights 2 are shown tosupport an idler pulley in a loop of each belt I to keep the belts taut.These features are all well known.

At the end of the reel comprising the spider above mentioned is mounteda cam bracket 3. It provides a pivotal mounting for a shaft 4 to whichis pinned an arm 5 whose free end is pivotally connected to a link 6. Tothe other end of the link 6 is pivoted a nozzle 'I made up of acontainer for the adhesive and a plurality of open-ended projections,each one forming a nozzle and all of them together constituting meansfor applying the glue or other adhesive throughout the width of the web.This nozzle may be provided with a source of compressed air or the likefor forcing the material out of it when desired and an air pipe 2D isshown.

The oscillating of the shaft 4 is accomplished by a worm wheel 8 and agear segment driven from any desired source of power that is reversibleand obviously it imparts motion to the nozzle I between the full anddotted line positions shown in Fig. 1.

Pivoted to the nozzle I is an arm -9 which is centered on the shaft I0of the reel. A stud II on the arm 9 constitutes a pivot and, as the arm9 is centered to the shaft Ill, this stud II describes an arcuate patharound this shaft as nozzle l is brought up to operating position.

A stationary cam path I9 is provided in which 10 a cam roller I8operates. This roller IB is pivotally carried on the nozzle structurebut on the opposite side of the stud II from the nozzle opening. As thearm 9 rotates, this roller I8 follows the cam and controls the motion ofthe 15 nozzle about its pivot Il so as to direct it at the proper angleto project the adhesive in the desired direction. This link and armconnection is duplicated at the other end of the reel and on each arm ofthe spider is carried a pivoted 20 arm I2 which is spring-pressed by aspring I3 in a counterclockwise direction, the necessary poppets bei-ngused to connect the spring with the reel and the arm I2. V

Onv each reel arm also is pivoted a latch I4 25 adapted to hook over aprojection I5 on thearm I2. This latch is pressed by a spring inaclockwise direction and is adapted to be released by the operation of asolenoid I6 at the desired time. When released, the spring I3 swings thearm 30 and its end operates against the arm Il of the oscillating valvecarried in the nozzle thereby opening the nozzle and ejecting adhesive.This action is so timed as to eject the adhesive at the time of therotation of the fresh roll S just 35 before the splice is to be made.

The forward edge of the roll S is cut to the proper shape and held downby a mild adhesive to allow the roll to rotate up to web speed until itis time to make the splice. 40

The spare roll S is brought by the rotation of the reel up against therunning web having belts I behind it and is rotated therefore up to webspeed and held at that speed. Now, at the proper time the solenoid I6 isoperated either man- 45 ually or automatically, releasing the arm I2.This action of the arm I2 opens the nozzle, permitting the discharge ofthe proper amount of adhesive. This adhesive is sprayed or forced outbetween the web and the running roll R and may 50 be applied to thesurface of either or both.

This method of applying adhesive between the forward end of the freshroll and the running web itself, on the incoming side of the roll, forengaging the splice insures that the adhesive shall 55 be applied justprior to splicing and while the fresh roll is running at web speed.Therefore, there is no necessity for having any adhesive on the roll Swhile it is being speeded up and no danger of getting adhesive on theweb prematurely.

In the modification shown in Fig. 3, the nozzle 1 instead of shootingadhesive directly out of the nozzle, is provided with a small sheet ofmaterial 28, such as paper, which has been previously pasted and isstill damp over the end of the nozzle. This sheet is shot by this nozzlein between the running web and the running roll. This serves to applythe necessary compound to attach the free end of the web roll to therunning roll S and make the splice.

Although I have illustrated and described only two forms of theinvention, I am aware of the fact that modications can be made thereinby any person skilled in the art without departing from the scope of theinvention as expressed in the claims. Therefore, I do not wish to belimited to all the details of construction herein shown and described,but what I do claim isz- 1. In a web splicing apparatus, the combinationwith means for supporting a web roll and a web tangent thereto and inconnection therewith, of a nozzle containing an adhesive located in theangle between them on the side from which the Web is running.

2. In an apparatus for splicing a running web roll and a running web incontact, the combination of a nozzle, and means for swinging said nozzleinto a position adjacent to the roll and between the roll and web whenit is desired to make the splice.

3. In an apparatus for splicing a rotating web roll and a running webmoving in contact, the combination of a movable nozzle located in thespace between the web roll and the web running toward it, means forsupplying said nozzle with an adhesive under pressure, and means formoving the nozzle into a position in said space in which it will directthe adhesive toward the point of the angle between the roll and the web.

4. In a web splicing device, the combination of a nozzle located betweena fresh web roll and a running web having means for ejecting adhesive,means for supporting the nozzle in movable position, and means formoving the nozzle as a whole back and forth.

5. In a web splicing device, the combination of a nozzle located in theangle between a fresh web roll and a running'web having means forejecting adhesive, means for supporting the nozzle in movable position,means for moving the nozzle as a whole back and forth, and means forswinging the nozzle on an axis as it moves.

6. In a web splicing device, the combination with a nozzle pivotallymounted, an arm supporting the pivotally mounted nozzle, a reversibleshaft, means for operating the shaft in either direction, connectionsfrom said shaft to the nozzle for moving the nozzle back and forth, anarm connected with the nozzle and having a projection, and a stationarycam for receiving said projection and controlling the position of thenozzle as it moves back and forth.

7. In a web splicing device, the combination with a support for therunning roll and fresh roll adapted to be located in such position thatthe web contacts with the fresh roll at the time of splicing, a nozzleadapted to project adhesive into the angle between the web and roll,means for moving said nozzle, a valve for controlling the nozzle, andmeans for operating the valve.

8. In a web splicing device, the combination with a support for therunning roll and freshroll adapted to be located in such position thatthe web contacts with the fresh roll at the time of splicing, a nozzleadapted to project adhesive into the angle between the web and roll,means for moving said nozzle, a valve for controlling the nozzle, an armon the support having means for operating the valve, a latch for holdingthe arm in inoperative position, a solenoid for releasing the latch, anda spring operative upon release of the latch for moving the arm intoposition to open the valve.

9. In a web splicing device, the combination of means forspeeding up thefreshroll and means for spraying adhesive on the fresh roll and on therunning web simultaneously.
